Question:
Answer:

There are different types of Omega-3 fatty acids, the short-chained which we get from plants, and the long-chained (also called EPA and DHA) which we get from fish and cod liver oil.

The marine Omega-3 fatty acids EPA and DHA are important building blocks and signal substances in the body. They have documented effect, for instance on cardiac health and the immune system, and are important for the development and preservation of the brain functions.

Plant-derived Omega-3 can to a certain degree be converted to EPA and DHA in the body, but a considerably higher intake is necessary in order to achieve optimal levels.
